Abstract (en)
[origin: WO2020222746A1] A printing apparatus is disclosed. The printing apparatus comprises a printhead and a controller. The printhead includes an array of nozzles, each having an actuator to eject a printing fluid, the array of nozzles having a first and a second subset of nozzles, wherein the first subset is located at the vicinity of an edge of the printhead. The controller is to assign a firing mask so that the actuators corresponding to the first subset of nozzles are instructed to eject the printing fluid with a higher energy level than the actuators corresponding to the second subset of nozzles.
